He posted on fanbox all the witches that are on the castle, they're all old posts from like 3 or 4 years ago, some of them are still just 2d art, some of them have beta models like this loli called ''Cambion''. she's the last one on ''the list'' if you can consider the gif where they're all...
You saw the scenes of the first episode as the roof...Gazer built that as the floor, at this point you should get used to it, tho I don't think he'll add anything beyond gore and shit.
Looks like he wants to make Kuro's brothers look older, but, considering the gore scene (which I like) in the most recent version, which already has the child brother, I don't get why, this post is from april, before Xen's Room.
